UK Driver Hours Rules 2025: What Every HGV Operator Must Know

If you run HGVs in the UK, 2025 has brought some of the most significant changes to driver hours rules in years. Whether you're a transport manager keeping tabs on compliance across a busy fleet, or a driver heading out on your first international run of the year, getting up to speed with these updates isn't optional — it's essential. Here's a plain-English breakdown of what's changed, what's stayed the same, and what you need to do right now.

What Changed on 21 April 2025

The DVSA brought new regulations into force on 21 April 2025, and if you haven't reviewed your compliance procedures since then, now's the time.

The 56-Day Record Rule for International Journeys

Previously, drivers on international routes needed to carry 28 days' worth of tachograph records for roadside inspections. That's now doubled. From 21 April 2025, drivers must be able to produce 56 days of tachograph records when stopped at the roadside on an international journey.

That might sound like a lot, but in practice it means your drivers need to have two full months of data readily accessible — either on their driver card or as printouts where necessary. Enforcement officers won't be sympathetic if records are incomplete. Make sure your back-office processes are set up to pull and store this data reliably.

AETR Rules for Non-EU International Journeys

If your vehicles travel between the UK and non-EU countries — think Turkey, Norway, or other AETR signatory nations — you must now follow the AETR (European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport) rules for those journeys. This brings the UK into alignment with international road transport standards and removes any ambiguity about which framework applies.

Goodbye "EU Law", Hello "Assimilated Drivers' Hours Rules"

It's a terminology change rather than a practical one, but it matters for documentation and training. The DVSA has officially replaced references to "EU law" in its guidance with the phrase "assimilated drivers' hours rules". If you're updating driver handbooks, compliance policies, or training materials, make sure you're using the correct language. Auditors and enforcement officers will be working from the updated terminology.

Smart Tachograph 2: Don't Miss These Deadlines

If there's one practical action item that deserves its own section, it's Smart Tachograph Version 2 (SMT2). This is the hardware upgrade that sits at the heart of the DVSA's push toward better digital enforcement — and the deadlines are coming up fast.

18 August 2025 — International Vehicles with Smart Tachograph 1

If your vehicles are already fitted with a first-generation Smart Tachograph (SMT1) and they're used for international journeys, the retrofit deadline is 18 August 2025. Miss this, and you're running non-compliant — which puts your operator licence at risk.

Book your tachograph calibration centre appointments early. With many operators in the same position, availability won't last long as the deadline approaches.

1 July 2026 — Lighter Vehicles (2.5 to 3.5 Tonnes GVW)

Vehicles with a gross vehicle weight between 2.5 and 3.5 tonnes have a later deadline of 1 July 2026 for SMT2 fitment. It's worth planning ahead rather than leaving it to the last minute, especially given potential supply and scheduling pressures.

The DVSA's enforcement focus is squarely on SMT2 installation and manual tachograph entries — so if either of those areas are weak in your operation, they're worth addressing now.

The Core Hours Rules: A Quick Reference

The fundamental driving and rest limits haven't changed dramatically, but it's worth having them front of mind — especially when managing drivers across mixed domestic and international work.

Daily and Weekly Driving Limits

• Daily driving: 9 hours, extendable to 10 hours a maximum of twice per week
• Weekly limit: No more than 56 hours in a single week
• Fortnightly limit: No more than 90 hours across any two consecutive weeks

These limits apply under the assimilated drivers' hours rules (formerly referred to as EU rules) for most HGV operations. The DVSA's Earned Recognition audit standards set clear expectations for how operators should monitor and record compliance with these limits — and they're a useful benchmark even if you're not pursuing Earned Recognition status.

Rest Requirements

• Regular daily rest: 11 consecutive hours
• Reduced daily rest: Can be cut to 9 hours a maximum of three times between any two weekly rest periods
• Weekly rest: Drivers must take a regular weekly rest of 45 hours, or a reduced weekly rest of 24 hours (compensated later)

If you're using software like TruckCheck to monitor driver activity, these are the thresholds your alerts and reports should be calibrated around.

What This Means for Your Operation Day-to-Day

Regulations only protect you if they're actually embedded into how your operation runs. Here are the practical things worth checking right now:

Record-keeping processes: With the 56-day requirement in place, your system for downloading and storing tachograph data needs to be airtight. Gaps in records aren't just an inconvenience at the roadside — they're the kind of issue that can escalate to a DVSA investigation.

Driver briefings: Do your drivers know about the 56-day rule? Do they understand what AETR means for their international runs? Brief your team clearly and keep a record that you've done it. The DVSA's Earned Recognition standards specifically call out the importance of driver communication and training as part of a well-run compliance system.

Tachograph hardware: Audit your fleet now. Which vehicles have SMT1? Which are going international? Create a retrofit plan and book calibration slots — don't wait until August to start making calls.

Wage and retention context: The 2025 road freight statistics show that between 11% and 26% of HGV businesses increased driver wages this year, with a median rise of around £1 per hour. Retaining experienced, compliance-aware drivers is worth investing in — a well-briefed driver is one of your best defences against an infringement notice.

TruckCheck is built to help transport managers stay on top of exactly this kind of day-to-day compliance work — from tachograph analysis to driver records — without the admin headache.

Stay Ahead of Enforcement

The DVSA has made it clear that roadside enforcement in 2025 is focused on tachograph compliance and SMT2 installation. That's not a coincidence — it's a signal about where the risk is concentrated right now. Operators who treat these updates as a box-ticking exercise will be exposed; those who build them into their systems and culture will be in a strong position.
